You can now share photo albums with other people using a web link created in the app. Another feature called "Free up space" will be a welcomed addition for those with little storage space; it can scan your photo library and delete photos off your camera roll that are already backup up in Google Photos.

Sharing an album in Google Photos works a lot like Apple's iCloud photo library; just send someone an invitation to the album (Google does it in the form of a web link), and it will prompt them to open the app and view it. Whomever you invite can also add photos and videos to a shared album, but Google doesn't have the ability to leave comments or like individual photos yet.

"Free up space" in the app's settings compliments Google Photos' unlimited backup quite well. It recognizes which photos and videos you already have backed up in the cloud and deletes them off your iPhone for you.

However, it should be noted that deleted photos will still show up in the "Recently Deleted" folder of Apple's Photos app, where they'll be completely deleted off the device after about a month unless you go in and do it manually.

The Android version of Google Photos was updated with the "Free up space" feature in November.
